luinë

blue

luinëadj. "blue", pl. luini (PE17:66, VT48:23, 24, 28, Nam, RGEO:66). Common Eldarin luini- would also be the stem-form in Quenya (VT48:24). Compare luinincë. Apparently -luin in Illuin, the name of one of the Lamps of the Valar (q.v.), Helluin, name of the star Sirius, and Luinil, name of another blue-shining star (or planet). (SA; Luinil is tentatively identified with Neptune, MR:435). Cf. also menelluin"sky-blue", used as noun = "cornflower" (J.R.R. Tolkien: Artist & Illustrator p. 193).

lúnë

blue

lúnë (stem *lúni-, given the primitive form ¤lugni) adj. "blue" (LUG2, LT1:262; later sources rather give luinë, with pl. form luini_ in Namárië)_. According to VT45:29, lúnë in the Etymologies was changed by Tolkien from lúna.

elw

lhûn

adjective.(unknown meaning)

This word, which also appears on the map of Middle-earth in LotR,
is glossed as "blue" in The Etymologies, but Tolkien later rejected this
meaning (as luin was already used in that sense). He
then proposed several explanations for it, including the possible adaptation of a
Dwarvish name into Sindarin, but he apparently never reached a definitive
solution.

Doriathrin

gelu

adjective.(pale) blue

A Doriathrin adjective meaning “(pale) blue” derived from the root ᴹ√ƷEL (Ety/ƷEL), probably from a primitive form *✶ʒelwā [ɣelwā] based on its cognates. If so, the [initial [ɣ] became [g]](/w/initial [ŋ], [ɣ] became [g]), the [primitive final [a] vanished](/w/short final vowels vanished), after which the [final [w] became [u]](/w/final [j], [w] became [i], [u]). These developments were noted by Helge Fauskanger (AL-Doriathrin/gelu).
